THEODORE J. STEEN, OF OAKLAND, NEBRASKA.

CHIMNEY CAP.

SPECIFICATION forming part of Letters Patent No. 312,918, dated February24, 1885.

Application filed June 18, 1884.

To a. whom it may concern:

Be it known that I, THEODORE J. STEEN, of Oakland, in the county of Burtand State of Nebraska, have invented a new and Improved Chimney-Gap, ofwhich the followingis a full, clear, and exact description.

The object of my invention is to provide a new and improved chimneycap,which is very effective, is held securely on the chimney, and can befastened readily and easily.

The invention consists in the construction and arrangement of parts, aswill be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a chimney provided with my improvedcap. Fig. 2is a cross sect-ional elevation of the same. Fig. 3 is anenlarged detail sectional plan view of one corner. Fig. 4 is alongitudinal elevation of a modification of the same, parts being brokenout, and others shown in section.

The cap is constructed with four upright corner bars, B, which havetheir lower ends tapered and bent outward or from each other, and havetheir upper ends bent to fit against the under side of a peaked hood, A,to which the upper bent ends of the bars B are riveted. Below the hood Aone or more rectangular deflecting-plates, O, are secured on the bars B,which plates are inclined'outward and clownward from the top to thebottom edge, the upper edge of each plate or deflector being flush withthe bottom edge of the deflector next above it. The bottomdeflecting-plate G has a downwardly-projecting flange, G, on its bottomedge, which flange fits closely on the chimney E. The deflectingplates 0have diagonal parts F formed at the corners at the upper edges, and theparts F are riveted to the bars B, which are placed diagonally at thecorners of the opening in the chimney. The bars B are faced down intothe opening in the chimney until the top edge of the bottomdeflecting-plate O rests on the top of the chimney E, and the flange Orests against the top course of brick of the chimney. The lower ends of(No model.)

the bars B are pressed firmly against the inner sides of the chimney,and thus hold the cap in place on the chimney. The flange 0 holds thebricks of the top course together.

In the modification shown in Fig. 4. the bars B are secured on the outersurfaces of the hood and deflecting-plates at the middle of the sidesand ends. The bars B are bent to rest for a short distance on the outersurfaces of the deflector-plates O, and then extend outward and upwardto the next defleeting-plate O, and have their upper ends riveted to theinner surface of the hood. The bars B are provided with longitudinalslots N in those part-s that rest against the bevels of the hood anddeflecting-plates, and bolts N are passed through the hood anddeflecting-plates, and the said slots are drawn up tight. Thus the partsof the cap can be adjusted when on the chimney. The lower ends of thebars B are forked, and are made to have more or less spring tension. Thecap is placed on the chimney in such a manner that the prongs restagainst the outer surface of the chimney E. The sides and ends of thehood A and the plates 0 are curved, as shown in Fig. 2, or are beveled,as shown in Figs. 1 and 4.

I am aware that a chimney-top has been composed of a series ofrectangular sections having inclined sides and open tops and bottoms,aroofed-shaped top, and bails for holding the said sections and top apartto form smokepassages. The lower section was provided with bentfastening-bars for securing the cap to a chimney. I do not claim suchconstrue tion as of my invention.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-- In a chimney-cap, the combination, with thebars B, having their upper ends bent, of the hood A, riveted to theupper ends of the bars, and the deflecting-plates 0, having the cornersbeveled and riveted to the bars B, substantially as herein shown anddescribed.
